Calif. May Build Tunnel in Quake Region
ALISO VIEJO, Calif. (AP) - Traffic is so bad along the eastern rim of Los Angeles' suburban ring that regional planners are considering the once unthinkable - an 11-mile tunnel through a mountain range in earthquake country.
Critics question the logic of building a multibillion-dollar project in a region so prone to earthquakes that an alternate proposal for a double-decker highway was deemed too dangerous. The tunnel would begin barely a mile from a fault that produced a 6.0-magnitude earthquake about a century ago.
"It's absolutely absurd to have a tunnel 700 feet below ground in earthquake country," said Cathryn DeYoung, mayor of Laguna Niguel and a vocal opponent. "I mean, would you want to be in that tunnel?"
Planners are due to make a decision in mid November on whether to pursue the project.
The proposal for what would be the world's second-longest road tunnel would create a new path between sprawling inland suburbs and Orange County, which has become one of Southern California's fastest-growing job centers.
Such a project could cost up to $9 billion and take 25 years...

The engineering can be done, and lets face it if a 9.0+ hits its not going to matter much where you are. Yes it may be close to a fault zone, but if the geology of the area supports it........

My concern is with the actual buiding of the tunnel. Drilling and blasting could actually create the quakes on a weakened faultline...
Oh geez sorry LA, we slipped a bit there. "hey Joe, easy on the TNT next time"

BANGKOK TRANSIT SYSTEM LIGHT RAIL ROUTE EXTENSION, THAILAND
The network comprises two lines, extending to a total of 23.1km
The cost of building the system was US$1,800 million (£1,100 million), which is almost twice that of a comparable line in Manila, Philippines. Lending banks were promised 680,000 passenger journeys per day (a 16% rate of return) but the present traffic of about 105,000 per day is only just covering operating expenses.

I agree, that area should be investing more in mass transit systems.
